So what's the alternative? Trust my ISP not to do the same? No thanks, I'll take my chances that my well-regarded and relatively cheap VPN service has both less resources to handle massive data storage for as long term, and is no less incentivized to turn huge profits or protect themselves by spilling everything to the government, even if both would under extreme duress. For what I pay, the VPN is a worthwhile little extra protection, not to mention the extra portable security when I have no choice but to use public wifi.
