At worst this only shows a lack of quality from Tesla, not from the whole industry.
FCEV has a lot of downside that BEV don’t, and same goes the other way. Those two technologies are complementary, but FCEVs lack the necessary infrastructure, be it for distribution or production.
Currently, most of the hydrogen used comes from fossil fuel as current electrolysis technologies have too much loss of potential energy, and has to be sold at a far higher price than fossil fuel based hydrogen as a result.
