In those two examples: serverless and wireless phones, it's not misleading consumers.
Serverless is a way to communicate that the consumer won't need to provision and maintain servers. It is true.
Wireless phone means you can move for quite long distances while talking without any wire connecting your device to the wall. It is true.
You may argue they're "misnomers". But to call it a "lie" is quite a stretch...
There is NO SUCH THING as serverless. There are always servers.
My wireless printer needs a wire for power.
My dog doesn't need a wire for anything, but no-one talks about them being 'wireless'.
(Come to think of it, my dog is serverless too...)
Indeed :-) But isn't this the same sort of definition you want for "serverless"? Not something relevant to consumers (e.g. "you don't manage servers") but a description of something where servers are not involved in any way?
