There is a hidden cost to every hobby and everybody is willing to tolerate a certain degree of shittyness.
I have a friends that has a rather old car and something on it is always broken. But he has no problem having 20 different apps for appliances, instead of deploying home assistants. Or having ads everywhere and even trying pihole or at least NextDNS.
On the other hand, I see my car as a transportation tool and when I need it I want to use it without worrying about some random part exploding. But I have no problem running Proxmox and hosting tons of services for my family.
That said, I would definitely not self-host something like NextCloud or any business critical component for my business and just paid somebody for the service.
It’s difficult to understand the move against custom ROMs. Especially considering the size of market for “weridos” that will spend hundreds of dollars on a device and first thing they do with it is unlocking bootloader.
Take that away and you go head to head against Samsung and Apple. And you will not win.
