I have been using it for more than a week and now am worried about the consequences that I am not sure are true or not!
I am worried that by allowing random users to surf using my network to prevent surveillance, someone will use my address to do malicious things, and I will get into legal consequences. Also, what if many services blacklist my IP address so eventually I get a lot of restrictions in my browing experience.
Furthermore, will this extension increase my fingerprint?
Are these thoughts valid, or am I just overthinking? If anyone knows, please comment.
Yeah. That's not a hidden risk, that's an up-front risk you accept by using the extension. You may want to not let it keep running while the browser is closed, which would reduce how long the connection lets others use your IP.
All extensions make a fingerprint more identifiable. This is usually only used with Tor if a Tor connection is blocked, so if you're just using this on Chrome or stock FF, yes, it will be very unique.
You're having valid thoughts - but what are you trying to do? Why not just use a VPN?
This would only be correct if this would be an exit node, which it isn't.
This extension is not about personal gain but supporting people who can't enter the your network due to their local legislation.
Your fingerprinting argument only works for exit nodes - there you're be absolutely right though!
Not all browser extensions are fingerprintable, only those that do by the website measureable differences to your browsing, which Snowflake, as far as I'm aware does not.
My ISP just aggressively blocking VPN and running tor network 24*7 system-wide doesn't make sense at all. To prevent network throttling I have to disable my VPN sometimes, and I only enable it when really needed which rarely bcz tor browser exist.
