No, I think they won't stop paying that fine. because they still have a great idea and have a lot of great partners in the liquidity service sector.
Why are they stopping when their businesses can make hundreds of billions of dollars in years to come?
Governments are stopping them because they can monopolised everything. After all Facebook is already huge and they can still grow bigger in the future if they released Libra coin. That's why at this point, US is targeting them because who would stop Facebook? So they are stepping up or at least tell Facebook that they are not in control here. If they are willing to pay that's fine but at least they know that the government is not closing their eyes on them.
France has already taken a very strict position. Their finance minister said that the country has got plans to block Libra EU because it han be a threat for their monetary sovereignty. Probably, it will not stop people from using Libra in case it is released, but as we see, Facebook will have to fight with many serious rivals to make its plans come true and not to start a scandal.
Which will be a long term rivalry for sure, Facebook already wide followers and supporters if most of them will entertained this new propose digital currency then it will threaten the economy of those people who will participate and start to use this system, Facebook will make a huge benefits
from this and will cater more and more people to use not only the social platform but also the digital currency that they'll offer.
