Open source/free software existed long before nebulous[1] terms like "influencer" came into fashion.
All it means is that you get the source code and some limited rights to modify, distribute and run the code. The rest is on you.
If you don't like the licence, don't use the software.
If you don't trust the author or group behind it, don't use the software.
If you don't think the project is well run or not, don't use the software.
If you don't like the politics of the people involved, don't use the software.
If the website "smells funny", don't use the software.
If you can't tell if the software is safe or not... you guessed it, don't use the software.
If you drink from puddles then it's up to you to decide if the water is clean or not.1. i.e. there is no definition in law to what this means.
