They were attacked by OSI zealots every time because it's not real open source. Which is true, but the unsaid - or well, only sometimes mentioned - other half is that these open source enthusiasts would you rather have a bog standard all-rights-reserved commercial licence than a relatively open licence without the four freedoms!
I can't claim to read other people's thoughts, but my hunch is that this happens because it's too "close" to an open source licence so they view it as competition, while they view commercial software as either a straightforward enemy or they don't care about it whatsoever.
The history aside, this approach just makes the open source community more and more irrelevant each day, especially with the advent of "vibecode your own dependencies up". The 4 freedoms come from a place where they were about users, but gigantic corporations have shoehorned themselves into being users, and instead of the community defending against it, they think the freedom to exploit the maintainers' work while contributing nothing back is more important than keeping the commons free and shared. :P
Only siths think in absolutes.
