Saving all of you a click: the article doesn't go into a concrete explanation of why they're not closing the last Blockbuster.
It has a theory, however:
>One possible explanation for the store’s long life: Bend is in a region that the city’s mayor, Sally Russell, describes as having “huge expanses with really small communities” that often do not have easy access to the high-speed internet necessary for content streaming.
>Many residents of outlying areas stop at Blockbuster during their weekly trips to town to run errands, drawn in part by the store’s seven-day rental policy, Ms. Russell said, adding that the store’s last-in-the-world status could even give it a lift.
