It's kind of a weird thing to gauge too. Even IF layoffs were to occur due to redundancies within the entity being acquired, is it still arguably a net positive for the industry? Thus far, every studio Microsoft has acquired recently has experienced considerable growth since the acquisition. Either in the form of bolstering the existing workforce of the studio, or outright creating new teams/divisions within them. I don't think Zenimax will be insulated from that phenomenon. Microsoft's acquisition of these studios are literally creating hundreds of positions that otherwise would not have existed had these studios staid independent and grown organically. That has to be a net positive on the industry. Can't say whether that'll be the case with other businesses acquisition targets, but I imagine that's not unique to Microsoft - at least in the short term?
The only people seeing this acquisition as a negative are..
1) People who have a personal gripe with MS.
2) People who don't know how corporate business works.
3) People who think the gaming industry should remain unchanged as the digital world continues to change around it.
4) People who don't know how corporate business works.
5) People who don't know how corporate business works.
If Zenimax was shopping itself around to be bought, then you've got to be led to believe that there were some financial issues going on. People fear consolidation, but what happens if Zenimax doesn't get bought? Could go both ways in terms of recovering from whatever troubles there might be, to include massive layoffs to keep the company afloat. Acquisitions can save companies, as well as the jobs that go with them. Can layoffs happen afterwards? Absolutely. You do what needs to be done in order to mold that acquired company into your vision, but that also creates new jobs as you say. This acquisition was bad for the fanboys, but great for the companies involved.
