It has huge implications because it makes competing in that market much harder due to licensing issues. Intel and AMD have a duopoly on the x86 market which compromises a huge chunk of server and personal computing, but that is changing fast. If they go ARM (or risc-v or whatever) they will have more competition to contend with, including their existing cloud computing clients designing their own chips and fabbing them with other foundries.
