Google is too big a company to let something this essential slip through. Therefore the only reasonable position is to assume it's intentional, unless somehow proven that it was just incompetence.
If intentional, that would count as a repeat offense. I hope EU regulators throw a crack team of coders/researchers at this, disassemble every last bit of binaries involved, check history of changes, turn Google offices upside down for relevant internal docs/memo's etc. The works.
Then -unless proven to be an honest mistake- fire up another anti-trust case. But this time tripling or x5 the fine.
A company of Google's size & influence, pulling this kind of shenanigans repeatedly, should either be forced out of business or become unprofitable. Oh and have the responsible leaders up top (CEO?) serve actual jail time.
