Third party cookies are far from being required by spam or scams and that's actually an example how one can make platforms safer while keeping them open and exchangeable, as for that 3rd party cookies ain't needed at all and it's not a tech to prop up their garden's walls.
> I enjoy looking forward to you educating people not install Instagram.
I never said anything about not installing Instagram just like I didn't argue those people should add doors or landlines to their houses ;-) So please, just stop it with propping up and taking down all those straw mans nobody talked about!
Rather, think common sense with a sexy lady offering their hot single friends to you, or some person offering you 10 million bucks as long as you can cover the small transaction fee of $1000, independent of the medium its send over (whatsapp, instagram, telegram, fb, irc, matrix, mail, ...)
And w.r.t your general suggestion that all devs just don't care about their users, it's anecdotal but personally I actually care a lot about UX and to offer users the information to allow them to make the right decision, that's one of main things I look out when reviewing UI or also API (as API users, even if developers themselves, are user too) patches, and I know quite a few other devs that try to do the same, not all "hate" their users.
> FB will spend $1B convincing your doctor that the FB App Store will cure cancer
Besides the point that they don't, that's again a complete straw man, nobody talked about that the FB app itself is a scam or evil or whatnot, it may even be, but that's not the point of the whole EU Act and your defense of Apples walled garden mechanisms like banning other payment providers, which still can and must be vetted to be even legal in the EU, or virtually breaking sharing of your data to other apps, that they can still vet and ensure basic security on.
