I don't think you watched the same Leicester game I did then mate. We tried to play the short-passing game, didn't get forward with it so knocked it back to keeper or defender who then hoofed it. We saw pretty much the same last season too.
I would agree Koeman is, at least currently, adopting a safety first attitude, and, as far as vocal posters on forums go, you're probably right with the "and if it continues it won't be tolerated by the majority."
But, if it's seen as a means to an end and a temporary measure, then the majority of Evertonians will be happy to go along with it for at least the rest of this season and probably next season too.
Don't be fooled into thinking a few noisy posters on a forum represent a majority. Most Evertonians are reasonable, patient people.
