Yes s/he is. Mitsubishi force you to use their Kumo Cloud controls, which are 1) expensive (a few kk) and 2) require cloud. Supposedly Mitsubishi is replacing Kumo with something else, but that just makes the problem worse.
Second of all, you aren't forced to use Kumo Cloud. Even though I have it, I still have a remote that operates the Split. No network or cloud required.

It has to translate a 2-stage signal into a fully modulating output, and it still seems to do a lot more on & off with high fan speeds than I would like or would be most efficient (as an aside, yes I have verified that the dip switches are in the correct position on the converters).
On the other hand, the unit at my in-laws tends to blow gently but consistently which is both more comfortable and more efficient.
