You haven't worked in any customer support position, and it shows. The amount of slurs hurled at them is far greater than anything found in a few github comments.
Also complaints that lack specificity must be aggravatingly common. I once complained on an open board about a bug in Wasteland 3 and a dev reading comments actually PM'd me asking for details. I provided details as best I could, including screenshots- the very next patch included a fix for my niche issue. But I imagine most bug reports being "GAME BROKEn! SUX! Fix NOW character creation BROKENN!"
Yeah that's pretty average for most bug reports. You're lucky if they even mention the issue, people like you who actually submit details are the only reason we can fix bugs lol.
