Good luck hiring enough people to maintain a billionty different versions of your service

  Websites don't run multiple versions of Wikipedia do they? Everyone would be on the same version, they'll just see different things.

    If there are 30 feature toggles, there would be 2^30 ≈ 1 billion possible combinations. Finding the combinations that result in something broken (through some unexpected interaction of features) would be impossible via QA. I guess you could keep a list of the more popular combination of settings and test those. More likely it means you'll let the customers do the QA for you. The customers will not like that.

    Not sure if you've ever worked on complex systems before, but features simply don't exist in isolation. Features interact - sometimes in complex ways, sometimes in unexpected ways. The cost of supporting user-facing toggles for every feature in your product grows exponentially. If you've ever maintained a system that uses developer feature flagging, the cost is large and typically this is for feature flags that should only exist for a matter of weeks or less.
