It's not that simple.
A character like Lara is a big deal. Which of course is the point of changing her to represent certain modern ideals. It's quite impossible to create a brand-new woke character and expect him/her to become as big as Lara was in her heyday. So these people must hijack famous characters and IPs to reach a sizable audience.
On the other hand, publishers are afraid that keeping "problematic" characters like old Lara exactly as they were 30 years ago would be bad publicity and would lose them customers. And of course they want to milk their biggest IPs, so they don't care if the character gets turned into a travesty of his/her old self if the name alone can get them a few million sales. Of course the IP will get tarnished, but they can't see that far and don't care anyway.
The devs don't really care, as they are the ones with the "modern" ideals who are changing classic characters to fit their agenda. Anyone who'd want to make a game with good old Lara Croft knows better than to work for CD, where most of the people who actually make the games will never let them do that.
