The App Store isn't evil because it filters. It's evil because it's a monopoly filter.

If there were lots of competing App Stores with their own beliefs, filters, prejudices, ideologies, etc - no problem. Of course this is exactly the case in the CRM industry.

So your conscience should be patting itself on the back, not beating itself up, when it tells a patent troll to go fsck a porcupine. This is exactly the purpose of a conscience: telling you to do what's right, regardless of the official structure of law in your era and country. Patent trolls aren't illegal, but they're evil, and it's wrong to collaborate voluntarily with evil. If the powers that be force you to collaborate, of course, that's something else...
