As long as there is a chain doing this, regardless of whether users vote with their feet (where the Gas is lower), It is better to vote with your mouth (criticizing other Layer 2s who refuse to give benefits to others as immoral). Other Layer 2s will also be forced to follow suit and give benefits to the people.
