Who cares what the average person will go through and do though? We’re each responsible for ourselves and how we choose to go about life, even if vastly differs from the general population.
The other is that once a tech choice becomes too niche, it stops being supported:
- Technically anyone can run their own email server but from what I hear if you do, some providers will treat you as spam.
- Niche features get removed from products.
- Some niche usecases depend on legal support. Running programs on a device you own without going through a gatekeeper ("sideloading") may be required in some jurisdictions (EU, any others?) but there's nothing stopping the almost-monopolies from making it impossible elsewhere.
