1) The people that live there live
near a theme park. They live
next door to a parking lot--not the same thing. Look closely at the map I"m attaching. Only a very few number of houses are currently
directly next to the park proper (which are at the Pony Express turn around, which is now enclosed due to their complaints). For the most part, homeowners can't even directly see the park, there's no real serious visual intrusions, and the parking lot is at least some buffer to sound from the park. If this particular plan went through, it would be the first time a roller coaster would be in their visual sight lines and have sounds aimed directly at them, and way closer than ever before. That's a huge difference, and not one a homeowner in that area would foresee. It's been a parking lot for at least 50 years, if not more.

2) During a visit to SFMM today, we drove around the neighborhood that is being developed near there. There's quite a few differences. First, the homes are set well above the vast majority of the park. From the neighborhood point of view, it's like SFMM has been lowered into a pit. The few rides that are higher are way, way off in the distance (one exception: Apocalypse's lift hill is relatively close). Also, if you actually drive down that street that's closest to the park, it's highly unlikely they'll be building any homes with their backs facing the park... the strip of land on that side of the street available to develop is maybe 3 feet wide? So any home you'll eventually see from the park will be the front, and there will be no exposure of backyards to the park guests. And there's a larger distance for sound issues.
Maybe Knott's has found a way to make this work, but they'll really have to smooth it over with the residents somehow (and especially with a nursing center and church in the mix as well, on the south side of the park). Scream shields or an enclosed drop are certainly an option, but that won't make most riders all that happy. What's the point of a 300+ foot drop if it's all enclosed?
