Indeed, they should start with the most damaging issues though, rather than taking the focus away from them in a smike-and-mirrors style distraction that is straws.
I keep two sets of stainless cutlery in all of my vehicles (little kits that include chopsticks) and have done so for a long time, for convenience and now also to avoid the wooden splinter-cutlery they provide now. Seems to work well.
As for plastics, most is not recyclable (even if it has the recycle logo) and some deep dive googling will demonstrate that. It ends up in landfill. Remember that post I did a out the oceans and another on general recycling which called out Amazon for ditching brand new (unsold) televisions into landfill because it was cheaper than recycling...well, that's where they should be focused, not on straws. There's hundreds of other examples. There's a load of stuff they could be doing but they do not because it restricts revenue...better to make the masses change their habits huh? The dual benefit us that the focus comes off the main offenders right at the top. Assholes.
