> I feel … I have been tricked

Everything “free” coming from a company means they’ve found a way to monetise you in some way. The big long ToS we all casually accept without reading says so too.

Other random examples which appear free but aren’t: using a search engine, using the browser that comes with your phone, instagram, YouTube… etc.

It’s not always about data collection, sometimes it’s platform lock-in, or something else but there is always a side of it that makes sense for their profit margin.
