Yes, I did own a dial-up modem. In addition to connecting to my ISP, I spent many years connecting to various local BBSes. The ISP wasn't the only reason I had the modem.

And, regardless, if my ISP stopped providing dial-up service, and I really still wanted dial-up service, I would have simply found another ISP to connect to. (After expecting my previous ISP to issue me a pro-rated refund for whatever subscription I was paying them.)

Also regardless, your analogy is bad, as the modem was a one-time cost. The issue at hand is that of recurring subscription fees Twitterific charges. If we were just talking about a one-time cost to buy the Twitterific app, I wouldn't be suggesting the refund that cost (except to customers who just bought the app right before the shutdown, perhaps; seems shitty to keep customer money when the product irreparably breaks a few days after purchase).
