Four car makers (Ford, General Motors (blog article), Rivian (blog article), and now Volvo (blog article)) have announced that starting about a year from now, their newly manufactured EVs will have a charging port that permits charging at Tesla supercharging stations. This will doubtless trigger the Osborne Effect (Wikipedia article):
The Osborne effect is a social phenomenon of customers canceling or deferring orders for the current, soon-to-be-obsolete product as an unexpected drawback of a company’s announcing a future product prematurely.
The term alludes to the Osborne Computer Corporation, whose second product did not become available until more than a year after it was announced. The company’s subsequent bankruptcy was widely blamed on reduced sales after the announcement.
