I did not intend to be confrontational and you are correct that talking up your company without declaring your affiliation is not against HN guidelines. I feel it is however a convention that is widely followed and for good reasons. Obviously your call at the end of the day.
TBF, they weren't "talking up" their company, they simply added the name to a list of companies doing something that's going against the grain.
To quote Bill Burr roasting Apple, there's a bit of "Einstein - Gandhi - Me" going on, but its way below the threshold for identifying themselves as a founder, IMO.
"Please don't use HN primarily for promotion. It's ok to post your own stuff part of the time, but the primary use of the site should be for curiosity."
I was not "talking up" my company. I made a reference to it, by name, on a relevant thread. This is well within the guidelines.
Had I realized that just listing my company name would create so many confrontational-made-up-rules responses, I would have gladly added [0] whatever disclosure comments necessary in order to silence the persistent self-anointed disclosure police mafia.
