From the article:

Though Tesla owners are typically quick to defend the company and Mr. Musk, several owners who spoke with Daily Kanban expressed frustration not only with their own inability to swap batteries, but also with the company’s lack of follow-through on promised leadership in battery swap technology. One owner characterized battery swap as a “no brainer,” while another questioned why the company promoted its alleged battery swap capabilities for so long without independent verification or more broad customer availability, saying “if you say you’re going to do something, you should do it.”
