It's an open conference offered by the largest player in the space vs. a shady deal between a supplier and ONE person of another company, without its employers consent, on top of that.
Taking personal kickbacks from vendors can be legal, so long as it's reported to your employer (and the IRS). What's not legal is hiding it from your employer because they have policies against it, and every (large) employer does.
The sole owners of large private companies can and do occasionally get personal kickbacks for their business. It rarely makes sense for them, because as owners of large private corporations they have better way of extracting cash from those companies (like literally paying themselves a salary or bonus). Totally legal, though.

Google the law of reciprocity. It’s human nature.
A marketing scheme intended to attract new customers is well within what's morally accepted. Also, it's not like every guy that goes to AWS re:Invent comes back with a brand new luxury car. What they get is just some good food and drinks, while they're there, and that's just providing good hospitality for your guests. It also does not happen behind closed doors, and most of the people that go are already existing customers.
vs.
Corrupt company approaches corrupt employee off the record to offer cash in exchange of contracts that would not get assigned to them otherwise (because if they were, they wouldn't resort to this).
"Let us take you on a $2000 vacation" vs. "Let us take you on a $700,000 vacation." One is objectively ridiculous - this is the difference.
In Vegas...
The answer is probably both, and any attempt to litigate it will probably be abused and lead to even more issues.
