This gets removed from EBITDA though, to avoid that accounting magic

Sort of. Depreciation is added back in, but at a lower percentage/year. 25% instead of 33%, since it's 4 years instead of 3 now.

EBITDA is earnings before interest, taxes, depreciation, and amortization

Yes. Meaning depreciation is added back in. But a different amount is added back in when you shift from a 3 year to a 4 year depreciation.
