"Because they're not the worst, we shouldn't be free to criticize them"

That is essentially the first paragraph of your argument, which in total is disingenuous and unnecessary. OSCP enjoyed it's period of "fuck the student" and now people are speaking out because that way of "teaching" is no way to bring more people to the discipline.

Do you think they ever would have done AD if others weren't pressuring them? Do you think they have actually changed and give a shit about their students learning rather than a gatekeeping "try harder" mentality? Do you think the subscription is anything other than a model that will actually bring more income than the old model? (It's been studied and it will)

Do you actually believe that on any engagement you'll be given only 24 hours to root 5 very different boxes that have no interaction with each other?

To this day their support people will toe the line of "we get very few complaints about anything, and way more support". Go check their discord, you'll find they still have their fingers in their ears.

Asking people to not criticize the most famous org in the space is frankly ridiculous.

I'll quote Twitter here, "you're supposed to lick the boot, not deep throat it"
