It is interesting that when Facebook and Twitter are confronted over some censorship they will often talk about needing to be more transparent over and over and over and over...
It isn't just getting kicked off the platform that you should worry about. You have zero control of long term pricing. Developers sometimes even develop without doing any math on what the services they are using cost in year one. Ask people how often they have already had to go back and rework code and shutdown servers because the bills coming in were out of control. The myth that you can just migrate if costs go crazy is completely nuts.
The link below is on historical gas prices. Also include a link on US dollar to Euro. Depending on the state we are currently at about 2.50 and have been over 3.50. The dollar menu going to 5 because of a 10% or 20% drop in currency doesn't seem likely. We, and also other countries, can have fairly big currency changes without much internal inflation or deflation(can depend on country size). A number of countries have actually deliberately devalued their currency in order to encourage growth. The question that is more interesting is can we lose high productively jobs(manufacturing...) and still keep high standards of living. The data indicates we cannot.
A 10% drop in currency would in your example, assuming no cost of shipping oil, US would go from 3.00 to 3.30 at 20% drop would mean 3.60 and even a US currency drop of 40% only gets you to $4.20. The data on trade indicates that countries that cheat on trade have epic growth rates and countries that do the "free trade" have close to zero growth or even declines. The data indicates local manufacturing has synergistic effects that massively outweigh the additional costs to consumers. See economist Ha-Joon Chang.
Point taken but the oil example isn't the best example on imports as we have since about 2010 really dropped imports with Obama's "All of the above" energy strategy which included opening the Arctic to drilling twice. Here is an example article on the subject: ...U.S. Exports More Petroleum Than It Imports In September and October

The US would benefit from a weaker dollar as it would protect what remains of our manufacturing base and also act as an export subsidy. Currency valuation, and in particular currency manipulation, is equivalent to a tariff or an export subsidy depending on which side of it you are on. Yes people like to pretend that if something goes up in cost 20 percent because of currency change that is somehow normal but slap a 10 percent tariff on something and that is completely different.
So given 68 million USA twitter users, if this rate continues, it wouldn't take long to get half the USA switched over. I am assuming most of the new users are USA. I suspect a fair number will use both systems for awhile. There could also be events like say a famous person moving over or being forced to move over that could result in even higher switching rates.
