As for my view, I think thats a bit extreme, though until relatively recently, Safari was slow to update and support many standards that came out in the last 4-5 years, though I think this is largely resolved, Apple does have some security and privacy concerns with APIs like the proposed File System Access API[7] that some feel is overblown and still holding the web back as a platform, specifically around gaining access to native functionality, particularly with iOS.
Also until very recently, their PWA support for things like push notifications were non-existant, they have slow rolled any web platform gains being supported on iOS and that could be perceived as protecting their App Store as the web platform becomes more app like.
My own opinion is somewhere in the middle, but this is the overall scope of the complaints summarized

I get everyone hates on Safari but it is legitimately also a different engine and they have shown to be privacy conscious.
Orion in particular is very good IMO
