I think the press release is actually clear that they felt this was necessary to retain talent:

> Engineers in particular have expressed their desire to focus their time on engineering, without being hampered by slow process flows

I'm guessing ASML had a lot of regrettable attrition and heard this in the exit interviews.

It's well known here in the region around ASML that they are very process heavy and things move slow. I'm not keen on working for them
