Same here - I’m more interested in a suitable alternative than to argue whether they are justified in their concerns.

I don’t think there’s a single right answer though. This terminology is used in many scenarios, each a little different and each with a potentially different answer

• Most git distributions now default to “main” and some variation of branch. It was a trivial change and seems as meaningful.
• Jenkins changed from master-slave, to controller-agent (or node). I’m still getting used to it but no big deal.
• Many DB or service distributed systems changed from master-slave(s) to primary-replica(s) and that also works
