Yep, you are right, its absolutely a stretch 
To summarize the above video, there are actual seminars made around milking the consumers as much as you possible can and targeting the minority labeled as “whales” with the intent to milk as much money as possible out of them. This tactic is something the Alcohol industry has relied on for years, relying on the alcoholics who spend everything they have on drinks. Its a lowly tactic to target people who can not control themselves.
Is this what Blizzard is doing? I can’t say, but its a weird decision since its inconsistent with past vendor mounts and its been done last minute and in a very sly and underhanded way. Blizzard only made a statement because their Feat of Strength was found and they were called out, I wonder how long they would have waited to say something had they not been called out.
Companies are doing this more and more by targeting what they label as “whales” and gouge them for as much money as possible. Its been bleeding more and more into other games lately though its usually used in mobile games.
Its predatory practices like this that have landed companies like EA in hot water with the House of Commons over in Europe with other countries like Belgium wanting to follow suit. With EA its loot boxes, with mobile games its micro transactions, with Blizzard it feels like its false scarcity through removal of digital goods that had no per-stated limited status at the drop of a hat.
So no, its not reaching unlike what you thought possible but a legitimate issue, a disease, in the gaming industry right now.
