So companies go there to die

Another way to look at it: When a companies bubble bursts, when people realise that it is just a note taking app (or whatever), and that its never going to grow 10x again, VC investors want shot of it.

Without a constant stream of new investment, the company simply can't afford to be loaded up with SV staff producing features that nobody will pay for. Bending Spoons change the business model to 'normal business'. They move to much cheaper European staff, stop work on nonsense 'features', concentrate instead on servicing their existing customers with a stable platform and well thought out incremental advances.

So they take businesses that are dying because nobody will give them free money any more, and make them into real sustainable businesses that can stand on their own two feet?

Nono, this is a pro-scammer point of view. They absolutely go for a minimal upkeep, maximum dark patterns strategy.

It's not about sustainable business, they are literally enshittifiers. I know quite a few employees, they literally debate whether a UX change to make a X to close a payment modal almost invisible is "too evil or not" and they go with it anyway.

So, we're not kind to companies who ruin their product for a short-term revenue increase then why all this positive spin for a company whose business model is to do exactly and only that?
