Transaction speed and cost is already a regular criticism of the Bitcoin network. It's so much of a criticism that the Bitcoin community made the Lightning Network and started pulling transactions off-chain and pooling them to address that concern.

But they didn't collectively decide to increase the number of allowed miner contracts. They literally built a second network rather than change the max block size.

And in fact it was not only not accepted, it was a big source of controversy to even try to increase the block size. That was the whole deal with Bitcoin Cash, people were outright hostile to this idea.
