No, and honestly I find people who choose not to read unfinished series kinda ridiculous. One as many people have mentioned, not reading an unfinished series actually makes it less likely to be finished. Two i hardly if ever just burn through a series, I'll enjoy one or two books and then read something else to avoid burning out on a series.

Three, most series including 95 percent of popular ones, get finished within reasonable schedules you're actually an outlier if you have crazy time between books. You getting burned by two series that are famously unfinished and constantly memed upon as works that will never get finished is not the same as waiting like two years for the final book in a trilogy; especially with how many authors now keep fans pretty well updated with their progress via socials.

Also modern series are now airing on the side of shorter for the most part ,duologies and trilogies, with the first books often being very satisfying in their own complete narrative arcs. Plus you don't get to participate in book discussions in the same way once a series is complete with communities having fan theories, art that's constantly being updated and just sharing questions you have with the larger community. They hype of waiting on a final release for a highly anticipated series is just a very different experience imo.
