They might have set up the user agreement for it. Stackexchange did and their whole business model was about catching businesses where some worker copy/pasted code from a stackexchange answer and getting a settlement out of it.

I agree with you in principle (hell, I’d even take it further and think only trademarks should be protected, other than maybe a short period for copyright and patent protection, like a few years), but the legal system might disagree.

Edit: I’d also make trademarks non-transferrable and apply to individuals rather than corporations, so they can go back to representing quality rather than business decisions. Especially when some new entity that never had any relation to the original trademark user just throws some money at them or their estate to buy the trust associated with the trademark.
