No one should be complaining about maintanance now adays. We have pythons, easy to maintain filter options, and if you don't like siphoning gravel why not go barebottom? That's what I did with a lot of my tanks.
The bottom line is, if you don't want to do the maintanance either:
Don't, and know that your fish might not be happy and will potentially die or have a shortened lifespan.
DON'T keep fish. or at least think about whether or not you really want fish. Fish are like any other animal, if you don't want to take care of them they suffer.
Set up your tanks for easier maintanance. If maintanance really bothers you don't just think about looks and decor, set up the tank for ease of care. This also means choosing your fish carefully. Don't choose a sensitive hard to care for fish if you hate maintanance. Some of my fish are rare and interesting but they're almost impossible to kill. Interesting doesn't have to mean a lot of work.
Downgrade to less tanks if possible. If you have a lot of compatible fish that can be mixed maintanance is actually easier on a larger tank but with less tanks overall. At least IMO.
Just know that you can generally only go so long without doing water changes and other maintanance. Some fish will appear fine, but generally the longer you go without doing anything it will bite you in the ass. Fish can appear beautiful, healthy and active for a long time and then suddenly they all have ich because of the water quality. Then you're stuck doing tons of water changes to get the nitrates back into wack and treating your fish and stressing them out even more.
The examples that people are using are EXCEPTIONS. You don't use exceptions to dictate your maintanance schedule or fishkeeping style.
Do you deny your other animals vet care and a good diet just because some people had dogs/cats that lived for 20 years roaming around outside with no shots, crappy food and poor care? Probably not, at least it wouldn't be a good idea.
