But the topic of discussion at hand is a contrast of launching a business in the person's home country or their current country. In that context the response makes a relevant point that deserves a considered response (or acknowledgement).

The comment was phrased in a way that could be construed as a personal attack and that's not ideal, but it can equally be read as a genuine point if we don't jump to the immediate conclusion that it was a personal attack - The point being: if conditions are more favourable in the home country wouldn't a rational actor move back to their home country and launch there, instead?

I don't agree with the OP by the way, but I interpreted the comment first in the way I described, rather than as 'grr if you don't like it go home'.
