Then you've missed the point.
Many folks are simply used to having the option of declining housekeeping through the use of DND signs. That's no longer an option at Disney hotels. That's why people are upset. Literally many hundreds, likely thousands of dollars spent on lodging at Disney for each party, and now there's zero expectation of privacy for those that want it.
So you say that "housekeeping have always been in the rooms every day I don't see what the big issue is." That's literally not true for many many people. It's true for you, but not true for a not-insignificant number of people.
So you may think "so what, coast2coastmickey, it's not your property, the owner has a right to enter." And I'd agree with you 100%. But, there's a difference between exercising that right every single day no matter what, and exercising that right when truly necessary. Those of us who are upset truly believe that exercising the right to enter EVERY SINGLE DAY is excessive when we've given no indication to the property owner that we aim to do anything wrong.
