I don't think it's fair to blame HP and Dell here; the greed of MPEG LA, which is increasing its licensing price, is the cause. It's problematic to globally allow the patent system and this kind of licensing; it's a real brake on innovation (and here we have proof of it). VP9 and AV1, for example, are not affected because they are free and open source.
VP9 and AV1 are less affected not because they're free and open source, but because they're backed by large-enough companies (Google) and a consortium that promised they won't claim royalties for the patents used in the formats. Companies outside Google or the consortium can still claim royalties, and indeed they do. See the Sisvel VP9/AV1 patent pool for an example of patent holders claiming royalties for technologies used in VP9 and AV1.
