> Changelog matters when your favourite app which has been free for the past couple years have decided that it’s monetisable now and there are intermittent ads in your feed.
That's a pretty uncharitable interpretation. After all, you used your favorite app for free for a couple years. Maybe they ran out of money. Maybe they tried to monetize in another way, but it didn't work and ads were the fallback to keep the service afloat (though also possible ads were the plan all along once scale was achieved). In any case, your favorite app isn't free to develop or host and you're not under any obligation to use it.
