> The FLAC and Ogg FLAC formats themselves, and their specifications, are fully open to the public to be used for any purpose (the FLAC project reserves the right to set the FLAC specification and certify compliance). They are free for commercial or noncommercial use. That means that commercial developers may independently write FLAC or Ogg FLAC software which is compatible with the specifications for no charge and without restrictions of any kind. There are no licensing fees or royalties of any kind for use of the formats or their specifications, or for distributing, selling, or streaming media in the FLAC or Ogg FLAC formats.
While I know through experience that you have a point about some companies avoiding anything that might be patent encumbered, and that the statement “[FLAC is not] covered by any known patent.“ would be a red flag to them, the argument falls down when we talk about how much code has been used over the years by companies who stepped all over the intellectual property rights of the authors.
Even if we look at Mp3s which are definitively patent-encumbered and commercially-licensed, here have been thousands of devices that played Mp3s before they a license (if they ever got one at all).
