Nokia blackmailed – paid millions
About six years ago, the encryption key for their Symbian mobile operating system leaked and Nokia was threatened with a release. Nokia paid millions of dollars, the cash was given to the criminals by Nokia officials in Finland with Police present as well however they lost track of them and the criminals escaped.
Symbian was the exclusive operating system on Nokia phones for a number of years but they continued to drop in market share and started betting big on Windows Phone OS instead. That did not improve their position much in the market, in the end Microsoft came in and saved the finish company by acquiring them for $7.6 billion earlier this year.
