I wondered about this as well when I began looking into BTC securities as most offerings have it now.
I personally included it in mine so that I ever get a solid offer to take my company private, the option is there.
This is what a motion is for. Raise a motion to sell the asset (hopefully at a nice profit). Shareholders like profit, motion passes, everybody wins.
Fair enough
I am new to this so was just going by other market offerings and what I figured was best for both parties.
I doubt the clause is placed into assets with some evil intent, more likely they did it same reason I did / for the reasons Meni mentioned.
I see where you are coming from however. While I doubt people placed the clause in their offerings with evil intent, I do agree the possibility is there.
There just has to be a better way, a better worded "out clause" for the maintainer that is fair to the investors as well.
I would be the first one to raise a motion to have mine changed should the community come up with one.
