Meaningless to the investors, including employees with vested RSUs. They got bought out at $54.20, way above the soon-to-become market value.

It was meaningless to Musk for all of about a week, when he came off his ketamine binge and realized what a stupid offer he’d made. But it was a done deal by that point.

According to Reddit[0], it might not have been meaningless to employees with unvested RSUs. They lacked an acceleration clause, so instead of immediately becoming 100% vested at $54.20, the schedule remained intact with a cash payout instead of stock. If the cash payout was relative to current company value, then it was a massive hit.
