For every product Google kills, it's launched dozens of wildly successful products you've been taking for granted for over a decade in some cases: Gmail, search, Drive, Photos, Chromecast, Chrome, Books, Flights, Scholar, AdSense, Calendar, Docs, Sheets, Keep, Translate, Maps...
Google can and does support dozens of good products, and pretending otherwise is getting tiresome. If your best criticism is, "I dunno if Google will support this long term" that, to me, means you couldn't come up with anything better to say, which means it's a pretty damn cool product.
