The exploit concerns most Tegra chips currently on the market, not just the Nintendo Switch. Those are used in, for example, cars. I believe that was part of the reason. Not to mention, it's not patchable without a hardware revision, so sharing it privately before sharing it publicly, while strongly hinting at that it's not patchable without a hardware revision (which has been done) has the same effect in practice for those wanting to escape Nintendo's jail, while letting those who use the Tegra in security-sensitive environments prepare adequately.
