The Reddit thing is disappointing. I stopped being a user a long time ago, but their links often show up in search results. I started noticing I couldn't see the page without logging in. I ended up blocking Reddit in my search results. It's not worth it.
At least for now Reddit doesn't require neither phone number nor email address (I think)
It requires email now. It used to not. And if you don't want to be shadowbanned you also need phone, and if you want to view NSFW you need government ID.
I just don't want to be logged in. I used to be an active user. It sucks up too much time and there's a lot of toxicity. I finally got off when they blocked third party apps. Their official app is horrible and the website has enough annoyances that I don't want to use it. I was content to click on the occasional search result though. Now that they finally took that away I'm done.
In practice you wont be able to comment if you don't provide email. Though, you will be able to view.
