Think about why you joined Lemmy. Reddit has been getting greedier and greedier, so you left to a place where the grass is greener. The same thing is true with Windows and Linux (and Linux is also much more big and mature than Lemmy). It attracts the same kind of people.
I stopped using BeReal a few months ago after they kept adding unwanted features (the entire point of this app was its simplicity) and my friends were leaving the app. Sad to see it has these kind of ads now.
