Thank you. I would do my best to improve real manpages. As I say in comments here, tldr pages aims to provide quick access to examples and must not replace real manpages.

How do you think, would I need to change license of a project if I want to push some examples to manpages?

If you're the author of the pages, you can set the licensing terms as you wish.

Generally, an MIT/BSD style license tends to be compatible with most other licenses. If you're the sole author, licensing the manpages under the same terms as the specific upstream works would work.

You might specify your own terms (say: a CC license), with a proviso "or, as an alternative, under the licensing terms of the original project for which this manual page applies".

IANAL.
