Things take timeThis companies technology is reshaping the industries bringing them into the future. These things don't happen overnight, it's a long process. And they are obviously upsetting alot of old timers with this tech, hence the constant assault on the company.
These legacy companies are all using out-dated torches, waste disposal processes etc, it takes time to shift everything over. And many companies are probably hesitant to switch until they have recovered, or at least paid for their last old style torches purchases, contracts etc...Not to mention these things need different infrastructure in place to even adapt these plasma torches. These things take time, it's not like switching from matches to a bic lighter at the corner store.
