Earlier quoted context omitted.
If it's about violations, or money, I can't strictly tell; it's one of those things that depends on who you talk to: http://lwn.net/Articles/475901/
The SFC's a 501(c)(3), so any money from the suits goes back into supporting their associated projects or supporting other ongoing actions.
If they're placing too high a monetary value on non-compliance with the license, then you could easily see why these companies would push back and seek these types of alternatives; or flat out deny the use of (L)GPL software in their products entirely. In the end, this is probably the opposite of what the SFC intended and may result in the loss of their greatest legal tool.
