Of course. I'll even quote the article:
> H.264 is a patent-encumbered codec; the MPEG LA organization requires developers who implement it to agree to a patent license. This license is fundamentally incompatible with software freedom. It requires developers to restrict how their software can be used, and to collect royalties in many situations.
While the wording is not perfect, this is actually about end user freedoms and convenience. There's the same situation is with parts of ffmpeg/libavformat or libmad - you just can't ship and use them completely legally. This is why "restricted formats" notion appeared, and why Ubuntu started shipping Fluendo's non-free encoder binary (http://www.fluendo.com/shop/product/fluendo-mp3-decoder/, previous-to-last paragraph).
It was always a problem (albeit, nowadays, minor one) to use proprietary codecs on GNU/Linux systems. Problem not on developers' side, but the for the actual end users. Killing H.264, thus actively encouraging WebM support helps WebM to win the formats battle. In a short term, both end users and developers will experience compatibility problems, but in the end - if WebM will win - both end users and developers will benefit.
And please remember that we have Firefox, which - due to various FLOSS reasons - just won't support H.264 anyway.
