> Why doesn't anyone get upset by the fact that the use of Executive Orders has been massively abused by both parties

Because all you can do in a two-party system is vote in the other EO abuser.

"Abused by both parties" is not a valid argument. Republican's use of EO are blatantly unconstitutional and they gloat about how it's unconstitutional, whereas usually Democrats' use of EO are deliberately designed to be within the rule of law or at least arguable as to whether or not it's legal. Republicans are pushing through whatever EO they want right now because they have a majority in Congress, which is at a historic level of dysfunction and corruption and will let the executive branch rule like a king.
