It's in the name: Prediction market. The point is to predict an outcome, insiders will naturally be better at that than non-insiders.
Though I think where things start to get a bit more insidious is when the "insiders" have access not merely to inside information, but the ability to change the outcome. That type of insider trading should be banned IMO because it works against the purpose of prediction markets as a tool. (Though the extent to which banning that is possible is debatable.)
That isn't very convincing, as the stock market itself is largely a prediction market. People buy stock to bet on future success, whether that manifest in the form of stock price increases, splits, and/or dividends. It's merely a much more narrowly-focused prediction market.
For that very reason, insider knowledge, and especially the ability to influence future outcomes, become the subject of heavy regulation. And, the lack of such regulation for congressional members is also why their net worth tends to skyrocket once entering office.
I'd argue that the "purpose" of the stock market is matching investors with companies that want liquidity. Allowing insider trading hurts the purpose by driving away non-insider trading participants, and it does not really help in any way.
With prediction markets, the "purpose" is information discovery, and "insider trading" actually helps (=> via information from insiders).
Disclaimer: I'm somewhat playing devils advocate here, I personally think that prediction markets are for now mostly an ineffective zero-sum game (and legalized gambling with all the drawbacks that brings).

Insiders bring information to a market. Intelligent analysis and prediction also does, but obviously insiders have special information they are incentivized to bring to the market. Most people placing these bets are simply gambling, insiders and analysts at least have rational reasons for placing bets and add information to the market.
If I use a drone to look over a fence to count the amount of inputs and outputs of a factory, and only I know this, it is perfectly legal for me to trade on it. Not insider trading! I'm just a really good information-finder and I'm morally just in how clever I am at finding an edge.
If I work at the company and count the inputs and outputs, and trade on it, I am a morally bankrupt scumbag and I have hurt society and all of the traders in the market.
If you work at the company you have almost certainly signed an agreement not to disclose such information; if you do so, you are violating the agreement. But that isn't insider trading.
If you hold a position of fiduciary responsibility within the company (or gain information from someone who does) that's a different matter. But the analogy there would be hacking into the company to read internal records, not just looking over a fence. in both cases, it's a crime.
The reason insider trading is illegal is because it undermines confidence in the markets by establishing a pattern by which insiders with privileged, secret information leverage it to profit off people who cannot access this information.
It also incentivizes insiders to leverage their position within a company to manipulate the business in order to profit. This also undermines integrity of markets.
Your second example, setting aside all your troll bait inflammatory verbiage about moral bankruptcy, is an illustration of this risk. I don't care if it rises to the level of moral bankruptcy, it is harmful to a capitalist society in a serious way.
Your first example is a depiction of someone leveraging information that anyone can gather. It does not undermine the integrity of markets because it is just an investor acting on publicly-accessible information.

But you don't usually buy the stocks from the company itself, do you? Unless there is some shenanigans with buyouts going on...
Companies can issue new shares to take advantage of positive public sentiment.

Seems like you should read more about these markets.
Insiders bring information to a market. Intelligent analysis and prediction also does, but obviously insiders have special information they are incentivized to bring to the market. Most people placing these bets are simply gambling, insiders and analysts at least have rational reasons for placing bets and add information to the market.
> Insiders bring information to a market [...] special information they are incentivized to bring
Simultaneously: Insiders have power to coerce an outcome, the market creates a corrupt payoff for them to abuse that power.
If I use a drone to look over a fence to count the amount of inputs and outputs of a factory, and only I know this, it is perfectly legal for me to trade on it. Not insider trading! I'm just a really good information-finder and I'm morally just in how clever I am at finding an edge.

Hmmmmmmm
