Gitlab's Series D was $100 million dollars for a valuation of $1 billion; settled several months (Sept '18 [0]) after Microsoft announced their plan to purchase Github (June '18 [1]) and in the month before the Microsoft-Github transaction was settled (Oct '18 [2]).
If the pitch deck to investors didn't mention Microsoft buying Github, I would be surprised.
Of interest, looking at their pricing page[3], Gitlab lists CI minutes as the top differentiating item for each level. I wonder if that's a signal of how the market has responded to segmentation ... or if it's as simple as "it looks better".
Disclosure: I work for Pivotal. We compete at the fringes and I expect there will be more as Gitlab expands its product boundaries.

Though nobody's plans survive contact with money and I would still bet on such a slide having been displayed.
Seems like it would fit better with IBM's (now) RedHat portfolio, than it would fit with Google.
Maybe I'm just being hopeful...
Another possibility would be Broadcom, as CA has a number of adjacent products for the software development lifecycle.
On the other hand Google is in a struggle to catch up with even Azure, so Gitlab looks attractive as a foil against Github.
Just look at Google+: it still lives on for G-Suite customers while the public version has been shut down.
I don't expect GitLab to be of much interest to Google though: A lot of their stuff competes with services Google has on GCP, Ruby/Rails doesn't fit that well into their Python/Golang/Java stack and a remote-only company wouldn't fit into their office-bound culture.
Gitlab is big enough that should they ever be killed by a Google acquisition (I don't think that's likely), a strong enough community would sprout and keep maintaining it.
I'm not challenging necessarily, I legitimately am interested in examples.
OpenSolaris -> Illumos
Hudson -> Jenkins
OpenOffice -> LibreOffice
MySQL -> MariaDB (not killed, but forked out of fear it would be)
And a non-Oracle example:
Node.js -> IO.js (arguable - forked because Node dev was stagnant, eventually merged)
I admit it's difficult to come up with examples, though I don't know of any failures either. RethinkDB has been sort of a failure, but it was never very popular to begin with.
If you told me 10 years ago I’d be way more interested in working with Microsoft than Google I wouldn’t have believed you.
