Before making any judgement either way, Sony & Microsoft's terms regarding the issue need to be ruled out. Yes they have allowed crossplay in particular instances but I'm not sure how that deal was done as it's not standard, and consoles manufacturers like exclusivity, the fact it was such a big deal that crossplay was enabled for a couple of games shows that much.
If it turned out that FDev's hands are tied by Sony & Microsoft in regards to account migration, any complaints about the issue really are for Sony & MS, and good luck with that. I would be reasonably sure FDev have approached them over the issue, and if not, they probably should, too.
Conversely, if it turned out that there are no such restrictions for FDev then it is really a matter to resolve internally and I can't see anyone having any issue with it being a one-time circumstantial deal for console users.
Either way, I hope a full migration path is found.
