Earnestly, what's the concern here? People complain about open source being mostly beneficial to megacorps, if that's the main change (idk I haven't looked too closely) then that's pretty good, no?
Mainly about the dilution of the term. Though TBH i do not think that open source is beneficial mostly to megacorps either.
They are claiming something is open-source when it isn’t. Regardless of whether you think the deviation from open-source is a good thing or not, you should still be in favour of honesty.
