News to me about the PC thing, Japanese publishers actually seem to be relying on the platform more and more, if anything. Then again I guess what I mostly know about are AAA and AA titles, but even recently there was a really niche Asian game that sold very well on Steam (honestly can't remember what it was, my bad). I think they sell pretty well if anything.
Switch is definitely a much safer bet though. Less competition overall and a lot of the Switch audience is probably inherited from the Vita.
I'd imagine they are talking about PC in Japan, but if they are talking about both Japan and the rest of the world, then I'd call them lazy and obviously seeking far less strife/competition (which is basically them wanting to be lazy).
That being said, I would like for them to continue publishing more games to the West on PC. if they don't, well I can always write them off the support list and simply support another publisher that will show care and won't be a lazy publisher who only cares about themselves.
