I'm glad you acknowledge that Moyes was under pressure on numerous occasions during his Everton tenure. However, the fact that he wasn't under that much pressure during that summer, far less than he was in say the 05/06 season or after we lost to the RS in 2012, gives you some indication as to where Everton were during that period.
We were in no position to just sack the manager and get a better replacement back then, whereas we just don't need to settle for the second class services of Roberto Martinez right now. We can attract and afford better, so why stick with the second rate option that is about to see us regress to consecutive bottom half finishes? We can do better, so why put up with worse?
