I dont think Messers Bates, Siniwatra and Kenwright are known to be the easiest to negotiate with. I may even speculate a damn site harder than Ashley in many ways.
I dont ask a question per se. I make an observation that where owners have pumped a lot of money in, negotiations have been closed very quickly, even if they are negotiating with difficult individuals (perhaps more difficult than Ashley).
The evidence seems to be, he has a price, they dont want to pay it, and he may be a bit dismissive in communications. If you want to buy and invest heavily, you would generally be expected to out this to one side and move quickly. In fact this has been exclusively done in football.
Generally the owners who haven't done the above, have tended to stall.
Now this doesnt automatically mean they fit into category 2 not category 1. But with the information we have, the view that they wont be investing in line with Everton, Chelsea and City would seem to be far more likely than they are. That doesnt make it certain, but it's unlikely given the information we have.
As you say, maybe renowned businessman Mike Ashley, who's done hundreds of deals is not only hard to deal with, but so much harder to deal with than a Shiniwatra, Bates and Kenwright (ah man Alex Ferguson personally highlights as being hard to negotiate with). I mean it's highly unlikely but it's a possibility I suppose. If I was laying either though, I'd be laying that they are just not that interested.
