Mozilla ponders policy change after Firefox extension battle (ars technica)

If Maone is adding countermeasures to the NoScript extension, the limit to what is justifiable in my mind would be to disable NoScript if AdBlock Plus is installed. After all, he is within his rights to not provide a service to people who refuse to compensate him. Interfering with other software on the system as he did though brings NoScript down to the level of malware.

Of course, if he wants the extension to remain free software, he wouldn't be able to stop others from removing such a check.
