Doesn't matter. They were promised more pay and got 0. Kicked and booted out of the door, despite them doing their job. Fuck Activision; they knew what they were doing, and did the same to developers and QA testers that weren't contractors. So fuck them and the whole, "Well, actually..." bullshit and "legal" loophole.
Well, no that's not actually what happened. Raven software told their employees that they would be getting raises, which they did. They went from $17 an hour to $18.50. They also didn't renew the contracts of a large number of their contractors. These are separate things that the article is lumping together.
That's the problem with being a contractor, you have no idea if your contract is actually going to be renewed. The promise seems to have been "next year QA testers are getting a raise" and they did. What also happened is a bunch of contracts that expire at the end of the year didn't get renewed.
The article is framing this as some sinister thing where the company is sacrificing a portion of its work force in order to be able to afford a raise for the rest of the people there, and that's actually not what happened. The raise is independent of the contractors that are being laid off. Contracts expiring happens at the end of every year and that's a totally normal thing in a ton of different industries, especially ones that have peaks and valleys in their work cycles.
What should be the focus here is that contractor work and the gig economy are fucked up and that companies including Activision Blizzard are exploiting contractors. That however is a major issue not just in the games industry, or even in tech, but it's a loophole that a lot of massive companies are exploiting for profit.
There was a recent referendum in California that wanted to re-categorize Uber and Lyft drivers as employees rather than contractors, which ended up failing because people were worried that the average price of an Uber ride would go up. We need more legislation for worker protections in general, and part of that is regulations of the gig economy and contractor work.
