In my area, they removed the data caps last year, when they also rolled out the higher upload speeds (eg the gigabit plan now has 350Mbps upload speed instead of 25Mbps). I don't think they've rolled that out everywhere though.
They also have a habit of keeping people on old plans that are either slower or more expensive. If you're still using Comcast/Xfinity, check their site and see what they offer to new customers at your address. (you may need to use an internet connection other than your Comcast one, otherwise they may detect that you're an existing customer)
I don't usually get involved in internet drama so I wasn't aware of this.
I started with Conduit. I hit some bugs though, and development was very slow. I looked at all the forks. Conduwuit was the most active, and all the issues I had were solved, so I used it. It got archived because of some other internet drama, and the readme said to use Tuwunel instead, which is what I'm using now.
Should I use something else?
I dunno. Use whatever I guess, as long as it's not Synapse.
