As the drizzle guys have pointed out in detail there are really two mysql customer bases. One wants to treat it as a sellable/supportable component of ISV packages, i.e. as a cheaper replacement for MSSQL/Oracle. The other wants to use it for "internet scale" things (high traffic websites, saas providers, etc). This price hike really only affects the former, and frankly, who cares, those guys have controlled the feature roadmap for 3+ years anyway they're welcome to pay for the mess they've created. Those of us who build websites will be just fine with Percona until drizzle is ready (or maybe even forever).
