Of course it's not, but characterizing tech workers in foreign cities as "colonizing" makes little sense, even if the various problems you're pointing to can be laid entirely at their feet (which, without knowing enough about Rome to have a high degree of confidence, I would suspect is inaccurate, you could just as easily be describing general gentrification which has good and bad components).
All in all this attitude seems to me to be more or less typical NIMBY-ism, just with a focus on tech workers likely due to your purview (we're on hackernews after all). And to be sure NIMBY-ism is not usually without good reason, it's absolutely a worthwhile and reasonable goal to preserve culture you hold as valuable, and indeed in the case of Rome there is some very special culture there worth preserving. But it should be noted that change is inevitable, and cultural isolation is not a reasonable way to accomplish this goal conducive to the kind of world we want to have (or I should say I want to have, highly mobile and integrated so your origins have little bearing on your potential trajectories, much more unified than it is today as a species rather than provincial squabbling).
Rather we want solutions wherein people can move freely and be accepted wherever they go, while also preserving cultures and spreading economic benefits in a more efficient way. For instance better taxation so nomads pay taxes where they are not where they're from.
