自由軟體基金會（FSF）發表公開信大力抨擊Mozilla轉而在Firefox支援數位版權管理（Digital Rights Management，DRM）的決定。自由軟體基金會希望Mozilla能夠改變決定，否則就不要再貢獻資源挑戰DRM，乾脆進而支持。
自由軟體基金會在公開信提到，他們能夠理解Mozilla是被勉強下做出支援數位版權管理的決定，但是幾乎所有瀏覽器也都宣稱他們是被迫支援的，自由軟體基金會認為這種說法並不負責任。
況且Mozilla跟Adobe的合作背負著原罪，Adobe是Mozilla與自由軟體基金會在意識形態上的敵人，自由軟體基金會說：「Adobe一直是自由軟體和免費網路的惡毒敵人」。如今Mozilla與Adobe成為合作夥伴，或許往後Mozilla將不會再對Adobe的行為作出正義的評判，甚至 會將Firefox的使用者送給敵對陣營。
Mozilla解釋Firefox支援數位版權管理的機制，將是讓使用者在沙盒中安裝外掛，以提供數位版權管理的功能，並非直接內建在Firefox瀏覽器中，Firefox依會是100％的開源軟體。
Mozilla這樣的解釋仍未平息自由軟體基金會的抗議，自由軟體基金會直指Mozilla踐踏自己多年來網路自由和標準開放的政策。
The Free Software Foundation says it is "deeply disappointed" in Mozilla's decision to support digital rights management (DRM) software in future versions of its Firefox browser and has published an open letter condemning the move.
Mozilla announced on Wednesday that it will work with Adobe to ensure that Firefox supports Encrypted Media Extensions (EME) – which are being added to the HTML5 spec at the behest of major content providers – even though it is ideologically opposed to DRM.
In an editorial posted Wednesday evening, the FSF characterized that choice as "unfortunate" and "shocking", and said Mozilla risked compromising the principles that set it apart from other browser makers.
"We recognize that Mozilla is doing this reluctantly, and we trust these words coming from Mozilla much more than we do when they come from Microsoft or Amazon," the letter reads. "At the same time, nearly everyone who implements DRM says they are forced to do it, and this lack of accountability is how the practice sustains itself."
The FSF was particularly critical of Mozilla's decision to partner with Adobe, which it described in its letter as "the company who has been and continues to be a vicious opponent of the free software movement and the free Web."
"With this partnership in place, we worry about Mozilla's ability and willingness to criticize Adobe's practices going forward," the FSF said, adding that the partnership meant Mozilla would be devoting some portion of its resources to "delivering users to Adobe and hostile media distributors."
Mozilla's stated plan is to build an open source "sandbox" technology that will allow users to install proprietary Content Delivery Modules into the Firefox like plugins. No DRM technologies will be built into the browser itself, which will remain purely open source.
But to the FSF – which is so zealous in its promotion of free software that it objects to the concept of open source – that's not good enough. By allowing Firefox to host proprietary components the sole purpose of which is to restrict users' rights, the FSF says, Mozilla is doing an about-face from its track record of "sticking to Web standards in the face of attempts to impose proprietary extensions."
The FSF says it hopes Mozilla will reverse its decision. But if it doesn't, the FSF's letter challenges it to begin "devoting as many of their extensive resources to permanently eliminating DRM as they are now devoting to supporting it."
笑死人～自由軟體基金會居然說「Adobe一直是自由軟體和免費網路的惡毒敵人」！顯然自由軟體基金會跟腦殘國一樣腦殘！
Adobe一直都是商業公司，又不是慈善事業，居然變成「惡毒敵人」？所以只要不是「自由軟體和免費網路」的其他所有公司，包括微軟、IBM、防毒軟體等，全都是「惡毒敵人」？
