I don't think that these are 2 lines of code. It at least has a way better price than raven b4 beta and staff respond insanely quick (once got a response in 3 minutes from them). Sure, 100$ might be a lot but the client is by no means bad. Their visual design is really good (not to mention every visual except for chams can be external), also has a very large variety of modules and is screenshare proof. The webgui seems cool, most people love the fact that it's launchable from your phone/browser, but of course it doesn't help in bypassing ss or such. Also most of their updates have the same amount of content as Vape and they support every version (which makes it one of the best end-game clients as vape doesn't support 1.16.5+ yet).
In that case, vape lite is also not worth the price considering they haven't had an actual update in 3 years now and has way less features than vape v4, just for an external gui and ability to bypass screenshares. I'd say 30$ is good for vape lite as vape v4 would be worth like 50$ and drip lite would be about 70$ (unless they do something stupid).
Drip's updates being small is just placebo. Most of the updates would be just ''silent'' updates since they don't really add a major feature to the client, like the friends system for example. Instead they're bug fixes.
