Yeah, that was my reaction, and it made me sad that Google has so eroded my trust over the decades that I was turned off at seeing an announcement implying they are deeply involved in core open source tools. I mean, who else but companies swimming in cash can truly deeply support this stuff, and for the most part, the people working on these tools really do care about the open source community. But Google's reputation is so tarnished that my gut reaction is at odds with my rational one, and that's a sad thing to realize.
I wasn't aware that the maintainer of Git works at Google, so I was a bit surprised by the announcement too. But it wasn't because of any drama like Google eroding my trust or whatnot, just that my information was incomplete so my gut reaction was irrational.
