Maybe, but if maintaining the current standard of the game requires the sacrifice of multiple human lives each year then it doesn't seem like there is much of an argument against downgrading.
Looking at accident reports, it sounds like there are some easy changes, adding guards to the machines and changing industry practices to de-energize the machines during the maintenance activity: https://www.atlantictraining.com/blog/bowling-alley-worker-s...
We must do something
This is a thing
Therefore we must do this.
There are other ways they could make the machine safer that don't involve adding strings and thereby changing the game.

It's even better when supposedly one of these deaths occurred due to "Extreme bowling" which apparently involves a half pipe. So yeah, this comes off as extremely misleading and just for clicks.
You'd probably save more lives banning all the beer and unhealthy food served at the alley, or by banning sports with a higher death toll, like soccer.
Strikes me as a way for alleys to operate cheaper by several magnitudes, and then just cover that up in safety rather than say "look people don't want to pay enough to bowl with machines"
Multiple can range from 2 to 2 million and magnitude matters.
