This is exactly what users want, though. Eg. if they want to receive updates more frequently on Ubuntu then they can use the six monthly releases, but most Ubuntu users deliberately choose the LTS over that option because they don't want everything updated.
When that happens, guess what you do? You trademark your software’s name and use the law to force distributions to not package unless concessions are granted. We’re beginning to see this with OBS, but Firefox also did this for a while.
As Fedora quickly found, when trademark law gets involved, any hope of forcing developers to allow packaging through a policy or opinion vote becomes hilariously, comically ineffectual.
The other alternative is to just not support Linux. Almost all major software has been happily taking that path, and the whole packaging mess gives no incentive to change.
Ban the user that did not read go to the distro’s maintainers first.
It isn't clear if this behaviour is legally enforceable. Distributions typically try to avoid the conflict. But they could argue that "we modified Firefox to meet our standards and here is the result" is a legally permitted use of that trademark. To my knowledge, this has never been tested.
On SaaS/mobile apps you have often daily new versions of software coming out. That's what users/developers want. They do not want 3 year+ stale versions of their software being 'supported' by a third party distro. I put supported in comments as it only really applies to security and what not; not terrible bugs in the software that are fixed in later versions.
Even on servers where it arguably makes more sense it has been entirely supplanted by Docker which ships the _entire OS_ more or less as the 'app'. And even more damingly, most/nearly all people will use a 3rd party Docker repo to manage the docker 'core' software updates itself.
And the reason noone uses the six monthly releases is because the upgrade process is too painful and regresses too much. But - even if it was 100% bulletproof, noone wants to be running 6-12 month out of date software on that either. Chrom(ium) is updated monthly and has a lot of important new features in it. You don't really want to be running 6-9 months out of date on that.
Do you have any evidence to back that statement up?
