Complaining makes sense if it is directly pointed at entities (i.e. all pools that signal BU instead of SW) responsible for Bitcoin not allowing to grow further.

Complaining is pointless also for the reason that if you want to enjoy faster confirmations, that you have to include higher than average fees. It's that simple.

If you're not willing to include a higher than average fee, then you have to accept the extra hours of waiting before your transaction finally gets its first confirmation. It's all up to the people.
