Always check the licence. Public domain, MIT, simple, plain BSD, GPL (any version), apache - if it's anything else, be extremely cautious.

Then again, GPL v3 is on many people's danger list
There are jurisdictions that don't recognize PD grants. I can't think of a good reason to use CC0 over MIT or BSD.
> GPL (any version)
This might be doctrinaire but I won't use the (L)GPLv3 because of the AGPL linking clause:
> Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such.
There's also the Zero-clause BSD License https://spdx.org/licenses/0BSD.html which is the same kind of thing except it does not even mention the words "public domain".
I would have too. I'm getting into Clojure(Script) where React(Native) seems to be a popular choice for UI. I haven't touched it yet. I hope there's a good alternative when I get around to it because I really like Clojure but I never wanted to rely on anything made by Facebook.
