We have the same in Germany with hundreds of "electricity providers" that themselves own no infrastructure whatsoever, just resellers. As far as I can tell the scheme is to aggressively recruit customers with signup bonuses and more, profit from the wholesale market as long as the prices are in your favor, and should the market turn against you simply declare bankruptcy and start over with a new company.

No we don't, those companies you're talking about are buying electricity on the market, they have no price guarantees by anyone, unlike in France.
