Why so negative?
They were nice enough to write a ch number that makes it obvious this aint a real chapter, lots of others don't even give a headsup like that for their april chapters.
Since it's obviously a joke chapter without even opening it, you're free to not read it if you don't want to, or read it if you're curious about what they came up with.
Personally I'd consider that one sort of kindness, not something to go all negative over. (Which often just lessen the targets willingness to work on something.)
