snowflake is a project by TOR that allows people to access censored services. Anyone can run a snowflake proxy. I'm using their firefox extension. more details here: https://snowflake.torproject.org/
The snowflake proxy acts as a bridge to the tor network at the entry side. If by repercussions you mean risk of exit-node traffic, there are none. It might cost a little bit of bandwidth.
There's the necessary info, thank you! - I've heard horror stories about hosting exit nodes, and was immediately spooked this would result in the same issues.
Indeed. This works because direct connections to the tor network are easily censored, but WebRTC is not (not without a lot of collateral damage at least).
I've been doing it for quite a few months now, and I haven't met any.
it's basically a WebRTC connection between snowflake extension, and someone using tor. WebRTC is a common medium for peer-to-peer communication, so it can't be blocked easily. Many popular services use WebRTC. e.g.: Matrix protocol, video conferencing services like jitisi meet, etc.
