Why would you give away your software source code free to anyone? (See rocketchip)

Lots of riscv implementations are closed source though

Also see XuanTie C910, open-source yet competitive with Cortex-A73, been available for years.

Meanwhile, Eben Upton has been falsely claiming that no such cores are available for licensing.

Exactly. Which potentially can make it worse than ARM, making it impossible for new players to enter the market at some point. Catching up would require massive investment and you can't just buy a competitive design of the shelf (looking at ARMs business model licensing your designs to other is just not a good deal and they are effectively still a monopoly in certain segments)
