When in reality, the original consumer considered this but would rather pursue a more active response than to sulkily and more important silently use something else.
Yes "voting with one's wallet" is certainly an option. But it should not be the sole option as you seem to suggest.
You can start a newsletter, informing fellow inflicted customers. Tell your friends and family. Launch a slandering campaign on facebook/internet (within the bounds of law, preferably!). Support a competitor. Promote fewer business regulations, so there are more competitors. Post on Hacker News. Etc &c, depending on one's disposition.

But I am also coming from a background where the governmental consumer watchdog is very powerful, so that colours my opinions on what can/should usefully be done.
