At the risk of being negative, can I just say that for me, as a consumer or customer, when companies start offering lifetime deals for a one-time fee, it's a huge red flag. Why? Because often it's a desperate move done by a company to generate cash flow. It's not ultimately sustainable either. Theoretically you could be providing that same service 10+ years down the track. You might (reasonably) assume some attrition in the time but you get my point. Too many times I've seen this done as a company's last move before filing for bankruptcy. Disclaimer: I'm speaking generally here. I know nothing of Mixpanel's circumstances (financial or otherwise) and certainly don't mean to impugn them, their management team, their founders or their employees. Providing a free service is different. Typically this is done as a "freemium" model where you hope a certain percentage of free users will later convert to paying users. People know this and have a different level of expectation than for something they've paid for, even if that something is a nominal one-off fee (you and they may also disagree about what constitutes "nominal"). As a paid service, due to consumer protection, etc you may have to meet a higher standard but IANAL.
