Perhaps I'm just being too charitable. Either way, the project rather rapidly seemed to come to the right conclusion and jump on board fixing their problem.
On a related note, I feel like this issue could be turned into a great teachable moment for OSS projects; one agH could use as a tech blog and guides for how to be a good citizen and avoid things that can make your project get rate-limited without you knowing.
Obviously, that's not to say the sentiment isn't genuine. The eventual conclusion makes it seem that yeah, they do appreciate what GH is providing and are trying to make it less strenuous on the servers to get a better experience all round. Making it work well is really in their best interests since the users are seeing a degraded experience until something can be done about it. Definitely also happy that the right conclusion was eventually reached.
Given how rapidly the same commenter changed gears, it strikes me as plausible there was an "ohhhhh eureka" moment, and suddenly the guy got it. His followup comments began dealing with the problem after a couple other GH participants explained further what was happening and why (as well as some actionable steps to take to correct the problem for good).
But perhaps I'm being too charitable.
If you are in such a position, then it seems like the best course action would be to ask questions rather than list off reasons that you don't want to deal with it.
