Something every car prior to this has been able to do without any impact on performance.

Which could be a reasonable sacrifice if you choose to make it. It's certainly not included in the marketing for these vehicles.

Running a heater is easier the less efficient your engine is, because there's more waste heat to work with. ICEs have the clear advantage there

If the energy is used for something intended (e.g. hot air) than it is not inefficient.

That's not really the context of the comment though. The point is just that an EV turns ~80% of its fuel energy into motion (with the rest as heat) and an ICE turns about ~30% of its fuel energy into motion (with the rest as heat).

If you need heat, an EV needs to turn more of its fuel energy into heat, while an ICE can just repurpose what was otherwise being dumped.

What is your point exactly? That EVs manufacturers should be held to standards higher than everyone else who markets products by focusing on the upsides? Or that we should continue to use inefficient climate destroying technology because it happened to provide a side benefit that we've become habituated to?

Eh, yes? They are presenting a new technology and want us to switch - they should prove their technology is superior.
