Of course we should have the right to repair. And of course many Apple users aren't okay with everything Apple does -- or you thought we were all mindless worshipping drones? No. We buy Apple because it makes the most sense for our needs. That's all there is to it.
But tell me, what choice is there out there if we want alternatives? No, really. Don't give me theoreticals and "if we could only do X...". We have Android and iOS. Nothing else. Sailfish OS is very niche and not everybody likes Sony's 2-3 devices that the OS supports. W10 Mobile is dead. Google and all Android OEMS actively sabotaged any and all open-source efforts -- mostly the ROM community -- mainly by voiding warranties if you touch a single byte in the bootloader. Even the rootless unlocking techniques are attacked on a regular basis. It's a furious battle and the OEMs won.
So don't tell me Android is much better than iOS because it's very obviously not. Historical factual records show that Google is very keen on the walled garden idea as well -- and I hope you are aware of the Google Play Services situation and that "the vanilla Android" (AOSP) gets less and less useful with each release and that more and more functionality is sucked into the proprietary, closed-source, binary blob that's Google Play Services.

Again, what other choice of mobile ecosystems do we have?
Android's supposed increased freedom is periodically strangled away (normal file system is soon going to be a thing of the past, for example). Looks like a pretty classical bait and switch, don't you think?
Oh, and the ability to side-load apps is only useful for the 0.2% of the populace that are tech-savvy users. For everybody else it's a huge security risk.
I understand you're not OK with what Apple does -- trust me, I hate their guts for some of their policies as well. We really don't have a choice nowadays though. Apple just seems like the lesser evil compared to Google.
