In an amended SEC filing ahead of its IPO, Reddit warned potential investors that "...on March 18, 2024, Nokia Technologies sent us a letter indicating they believed that Reddit infringes certain of their patents.

That’s not even close to the full story, and partly straight up incorrect.
They sold their mobile branch. The brand of which eventually ended up with HMD global, which now makes Nokia branded phones.
Nokia Oyj is a telecom RnD and infrastructure company, as in the hardware and standards behind wireless communication tech. They never stopped.
They essentially pulled an IBM and exited the consumer market, but they never ceased operation, or sold off their main business.
Microsoft has had absolutely nothing to do with Nokia Oyj since buying their consumer handset branch off them.
And even back when Microsoft bought the mobile phone operations the company making the phones was Microsoft Mobile and Microsoft only leased the brand name from Nokia to use on their mobile phones for 10 years - same as with HMD Global today.
