Glass is not all it's cracked up to be.
Check out

You will find threads on hospital visits due to glass, lost batches due to glass, therapeutic threads where a guy smashes all of his glass and switches to better bottles...(which are clear for the fermentation watchers)
There are defenders of glass, but they are a minority as people see how well the food safe better bottles work.
They are lighter, non breakable, non-oxygen permeable (as far as I can see from 33 or so batches in them).
This isn't a partisan debate.
People tend to defend whichever they have.
I can't have those big glass bombs around my kids. End of story.
