I don’t think they are thrilled, but I would expect them to have some non-compete clauses in their license that would give them some say WRT ARM’s pricing overlap with their products. No contract can legally forbid ARM from going after Ampere’s customers, but there can be penalties in terms of reduced license fees.
OTOH, I’m not sure how far Ampere’s work with Oracle Cloud and their hard booked orders give them a cushion. I haven’t heard of new products from them, and haven’t played with OCI for some time to see if there are any newer CPUs there.
