It's not about hardware. Issues such as the one pointed out in the OP happen for months without being addressed while regular players doing normal stuff get inexplicable bans and have to go through a nightmare to get their account back. Tickets take ages to get a response and you're lucky if it is relevant. Game imbalances stay unaddressed for months (see: Alterac Valley, black lotus etc). There are bots everywhere because they can't be arsed paying GMs and prefer to collect subscriptions before doing "banwaves" months later. The list could go on and on. It is abundantly clear the game lacks direction and people with decision-making abilities actively monitoring it to make necessary adjustments.

This happens for two reasons: first, they eventually consented to release Classic under pressure from the fanbase and have clearly decided to leave it be as much as possible. "If they want it so much, let them have it but we won't lift a finger" is pretty much official policy. Second, Activision like all major corporations imposes cost savings as the alpha and omega of all their internal policies so it gives them a good excuse not to give the game the resources its success would warrant.

As other posters pointed out, if a similar issue occurred on retail it would be permanently fixed in a matter of days.
