It looks like an attempt to reinvent the GPL. The wording is a bit
sloppy at places, but I didn't find anything in the license itself I
would call nonfree.

The trademark clause is actually nice, and could be used as a model of

It just says "beware that this is not a trademark license", and as
such it is a legal no-op - a license that did not say this explicitly
would not be a trademark license either.
The problematic kind of trademark clauses is the one that says "you
lose your _copyright_ license if you use our trademark in ways we're
not happy with".
