While there's some overlap, Lightspeed and Highland aren't directly copying YC in the same way as the complete plagiarism of Techstars.
Lightspeed and Highland are doing this more for marketing than profit. They're not even taking any equity. It gets their name out to entrepreneurial students at colleges and that's about it. Anyone that gets a grant will pitch future startups to the VC that helped them get started. To the VCs, it's worth spending a mere $150,000 to build a strong relationship with some of the best young entrepreneurs. Sure, most of the startups will go back to school after the summer program instead of dropping out and being successful but they'll come back to Lightspeed or Highland for funding after they get their degree.
Highland also funds biotech and provides lab space in their incubator. Neither one is targeting the same uber-hacker that YC prefers.
I think you should be flattered you began this trend of micro-investment. It's a great idea. I'm grateful because it's better for all us young entrepreneurs to have as many options as possible.
