Sorry, I am not Russian, but in my opinion they were not too badly burned.
Sure, they wanted those vessels and would have them both in service by now, but instead they got complete specs for the Mistral class carriers and they got to build half of them... I rather suspect they likely would have operated them for a few years and then signed a contract to build two more in Russia, but also likely further joint contracts to build vessels could have followed if everything went to plan and their satisfaction.
As it was they will likely never get another major military ship build in France again, which is pretty understandable, but they pretty much got money back, got full intimate details of a working Helicopter carrier and most of the internal components they developed for their ships are likely to be kept on the Egyptian ships, so there is now a foreign market for their naval helos.
I rather suspect they will develop their own helicopter carrier designs, likely with modifications to more suit their needs, including much better armament and facilities to better suit their equipment like ice breaking capability and allowances in size for their taller coaxial design helos.
