Adjusted means you made a profit if you ignore the fact that you made a loss.
Especially when servicing interest on debt (the I) isn't nearly as cheap as it used to be, unless the debt is locked in at a lower interest rate. Even if it is, but the term ends, a rosy-sounding EBITDA can turn ugly.
"Adjusted" EBITDA is frankly a sign that the company is making "magic" (read: misrepresentations) on its balance sheets. It's not surprising that Airbnb, Lyft and Uber are the only prominent companies using them.
Uber has been adjusted EBITDA profitable since 2021 and is close to GAAP profitability (might reach it this year or 2024).
