Why? Project & copyright owner can decide what he accepts to his
project / code. GPL guarantees that others can fork the code if they

People have their own opinions on matters and often the opinions (or
how/when they're expressed) conflict with yours or mine, that's just a

needed to avoid the freedoms from being corrupted by a gradual slide to
pragmatism and what is convenient. Such people may be awkward to deal
with, but one needs to admire their persistence. You can get them to
change their minds, but it requires finding an argument that works from
their own principles, not yours. And it requires time...
