Usability and killing a useful industry

Joel writes about Microsoft's Antispyware.

          Not only that, but I wonder if Microsoft can run an antispyware product without huge conflicts of interest. For example, will they block all the spyware that Real installs on your system? While Real is suing them? Especially when blocking spyware from Real will just give Real more ammunition to use against Microsoft in court? And the next time Microsoft needs a DRM favor from your friendly neighborhood media conglomerate, will the media conglomerate demand exemption from Antispyware removal for their adware in exchange for supporting Windows Media 37.0, with the new brain-zapping feature that prevents you from humming any song unless you bought the performance rights? (A sheet of tinfoil wrapped tightly around your skull is effective against this zapper, I understand.)

          I understand that Microsoft wants to help customers who feel like a spyware-free operating system should be your right when you pay for WinXP, but it's a shame that by giving it away free they're likely to wipe out a useful industry and replace it with something that's difficult to trust due to conflicts of interest.
