If you want to get a programming job, you want a good looking CV. By contribute to prominent open source projects on github, github’s profile system helps by making it look real fancy.

At least it used to be good, now it’s a magnet for lazy vibe coders spamming their shit everywhere to pad their profiles. On other git hosts without such a fancy profile systems, there’s less on an incentive to send slop with far less benefit to their CV.
