The other day my Windows locked behind an advertisement for Microsoft's backup services, trying to trick me into surrendering all my private data to their servers. They even added a typical dark pattern that on clicking "No" another "But... We recommend it, are you sure?" appeared. What a disgrace to push such an ad on people's computers. This abusive behavior is their company culture.
