Please note this change has no impact on our existing customers, including those using the free version. I give it six months before they start strong-arming free users into paid accounts.
Note that per user limits continue to apply, so people have as much incentive as they ever did to upgrade, plus for any new domains/projects people will naturally either migrate to other options (then consolidate services around these, moving themselves off Google) or start paying.
Not convinced there's any need for hostility on either side.
