One cannot take photographs of many real-world objects

encountering trademarks. Cars bear trademarks (their manufacturer's
emblems, names, sometimes even shapes or paint designs). Streets are
covered with trademarks. And so on and so forth.
I hope that such are not included in any restrictions.
This is where reasoned community consensus can resolve the issue nicely.
Incidental use of a trademark is not typically a problem, as compared
with actual simple reproduction of the trademark.
To make a simple example:
A CocaCola logo in and of itself is not appropriate for commons.
A photo of a CocaCola bottling plant, which contains the logo as part of
a sign, is appropriate for commons.
Borderline cases can be discussed and debated with a view towards
balancing competing interests.
