Unless Linux violates IP rights, it will fail to deliver innovation over the long run. This final remark is worthy of an essay all by itself. As propaganda, it has a superficial cleverness. It's a perfect FUD tactic. There are lots of pragmatic and legal reasons to believe this FUD is a phantom.
Nobody has a natural monopoly on talent.
If these claims are not credible, neither is hers. If we believe Ms. van den Berg means her claim, we must deduce that Microsoft actually cannot imagine anyone inventing innovations that don't violate existing IP rights. Perhaps this is understandable, giving Microsoft's own long record of buying or outright stealing key technologies rather than innovating. Microsoft truly behaves as though it corporately believes that there's only a fixed pool of key ideas, most already discovered, which software designers must squabble over in zero-sum competition until the end of time. The interpretation of Ms. van den Berg's parting shot kindest to Microsoft, then, is that it is a lie intended to frighten the gullible.
