Yyuuuppp. Came here to say this. I've been a web dev since before mobile responsive was a thing. I miss the "User comes first" outlook. Now, job applications scream for devs who understand good user experience. Then, when you start working on a project, there's some user experience concerns, but it all gets thrown out the window for the sake of ads, pop-ups, whatever. I've had so many heated discussions in meetings about the trashing of UX.

Oh ya. I have researched the topic heavily, and am a front end dev, who has done a LOT of SEO work for marketing/advertising firms and SEO focused companies. The tools are very scary, even at the free tiers.

I would very much like to see this go to trial. Not specifically about tiktok, but it might start to shead some light data tracking and privacy by apps in general.
