This doesn't convince me. As a consumer patents and patent lawsuits are almost always bad. Patents reduce options in the market, lawsuits between companies waste resources, startups being acquired reduce market options. The only real argument is that it will prevent communities from forming. But I don't buy it. Open source needs competition too, monolythic ecosystems are bad. As an example, Apple didn't want to contribute to gcc so they created LLVM which is a boon to everybody.
