Your WhatsApp support isn't yours. You're renting it from Meta.
The moment they decide your quality score dropped, your entire customer channel gets locked. All those conversations? Gone. Support tickets? Stranded.
If one platform can kill your urgent support overnight, you don't have a channel strategy.
You're in a hostage situation.
This applies to everything in crypto too. Centralized platforms, custodial wallets, even Discord servers. You don't own the rails, you're just using them until you're not.
Build on infrastructure you control. Own your distribution. Own your user relationships.
Otherwise you're one TOS update away from zero.
