I'd encourage you to not strawman my response. Because I already said myself that it appears to me it's only hobbyists who are losing support.
My objection isn't to the argument that it's dropping support, my objection is that it's dropping support without cause. Other than, the assumed this would be more comfortable for me.
Maintainers are absolutely not required to support everything for ever, but I recall a story where someone from Linux paid for a user to upgrade, not because that was required, because more because that would make dropping support for that floppy driver feel ethical.
This is the level of compassion everyone should expect from software engineers in critical positions of power.
I have no sympathy for people who lack the compassion to expend the effort to help others. I do have sympathy for people who have to watch the world that they, even if it's them alone. Have to watch their world get worse, so that others can avoid a trivial amount of perceived discomfort.
Should this solo maintainer (who understands C) be required do things exactly the way that I want? Of course not, but I'll be damned if everyone expects me to remain silent while I watch them disrespect other people who were previously depending on their support.
