My advice, assuming you're on HN with a technical background, is to create your own bot for monitoring product availability on your store of choice. It's a pretty small investment of time, and it frees you up from the time spent watching a Discord or refreshing store pages manually. Set it up to poll at a reasonable frequency, set up some form of push notification, and find that it's not that hard to get ahead of the horde who are all relying on someone else to do the dirty work for them.

Someone who got a launch day 3090 from the Nvidia store
On the other hand, I did get a 1080ti several months after launch during the crypto-boom of 2017 using the same approach. I have also stumbled upon lots of "we added more tickets to X event" type situations before they are announced on social media and disappear in an instant (think sold out music festivals and concerts).
My goal is just to mimic me sitting at my laptop refreshing a page trying to buy something as soon as it becomes available, so that I can use my time for something better.
Trust me, there are people sitting there refreshing the page more often than 1x per minute, and as far as I know they didn't run into any blocks either.
I believe nVidia once had a policy of deliberately crippling the double-precision performance of their regular consumer graphics cards, in an effort to push their high-end computation-friendly 'workstation' cards, but that's not quite the same thing.

Anyway, there's blame to go around, and these days I'm more inclined to look at how poorly retailers handle it. There are few (or none) backorders or queuing, and sometimes easily gamed systems. Either way they get their money, but it's not a good look. (It is not the end of the world, but annoying and doubly so when so many of us are stuck inside. Certainly much worse problems to have, I know.)
There is a huge amount of CFAA or worse stuff that needs prosecuting - it isn't just bots placing orders, it's mass amounts of hacked machines and hacked phones being used as proxies and cookies stolen for a valid fingerprint/less CAPTCHAs, wire fraud and forgery of documentation being accepted (instead of RPKI/proper filtering)
Anyone that has a slightly popular (at all, really) will get shady requests asking to "install a SDK" or "buy your extension" which installs malware on your end-users devices. This is the slightly legal/grey area part. The other part is where AFRINIC recently revoked a /14 for fraud that was nearly entirely used for proxies and abuse by a 1 person US company, based on WHOIS remarks, obtained fraudulently.
