You could say that.
Just like I could say that WoTC, and D&D, exemplify the worst of modern corporate practices in that the risk is offloaded to the employees ... sorry, there are almost no employees working for D&D ... "independent contractors" while the parent corporation retains all of the profits in order to distribute those profits to its shareholders. And while they certainly strive to make people feel good (and I genuinely appreciate that they do their best to make the game more inclusive and representative), they are not particularly good corporate citizens in terms of their actions.
Sure. TSR did engage in litigation (who doesn't ... what, HASBRO doesn't sue people?), and TSR had its share of issues, including eventually going out of business, not to mention laying off people. But at least they were employing people to lay them off.
Regardless, any company that employs creatives and allows for that much amazing work deserves to be lauded. Given that the vast majority of Hasbro's D&D output is derivative of TSR's original work, or, at best, derivative of WOTC's M:TG stuff, I'm not sure I would be so quick to discount the original TSR. Especially when one of your points is:
And lets not forget that TSR was the brand associated with D&D during the satanic panic.
TSR standing up to the scolds and fearmongers of the 1980s, given the atmosphere of the time, was a profile in courage. Not something to be sneered at.
Just saying.
