SpaceX rockets have an unfortunate tendency to crash and burn
No, they really don't.
SpaceX has had some accidents (it is rocket science after all), however they're up to something like 16 launches this year, including 3 re-using previously flown first stage boosters.
They may over promise on delivery dates, but as the company with the most launches in a single year to imply a high failure rate is disingenuous at the least.
