Well, if you want to get technical, they also slowed down on full episodes on their main channel. Yet, they uploaded one of their full episode compilations today for the first time since a few weeks ago. Longer than their last classic episode upload. A short break in-between is hardly worth concluding that they are done with full episode uploads. Yes, it's very well possible that they slowed down a little because of their Tubi uploads. It is after all, the most classic Sesame Street that has been available since being removed from HBO Max, so even though YOU might not appreciate that, there are some people like me who are glad the episodes are made available again. Plus, it's already been confirmed that 10% of the Sesame episodes on Tubi are going to be rotated out every quarter with other episodes, so there is STILL the possibility we might see other new to streaming episodes in Tubi in the future. Personally, I would prefer that over the YouTube uploads, since those would not have the Sesame Street watermark, and has captions and subtitles and everything.
Secondly, if/when they upload their next classic episode, there's a pretty good chance it's going to be another HBO Max episode. AKA, one already on Tubi. What would you do then if that happens? Are you going to celebrate and rejoice that Sesame Workshop uploaded another classic episode on YouTube. Or, are you going to whine again that we've already seen this one before, and that it isn't a new to streaming episodes? Knowing you, I'm willing to bet it's the ladder.
Plus, it's not like there isn't already plenty of ways to watch classic Sesame Street content online. Especially now. If you're really craving classic Sesame Street content that much, then you can look through all of the various uploads on YouTube, and even archive.org. There is no shortage, you don't have to rely on Sesame Workshop just to watch classic Sesame content.
It's honestly amazing to me that you're older than I am. And I'm in my 30s, yet, I've seen 12 year old Twitter users show more maturity than you. Heck, even modern Sesame Street counterparts feels more mature than you do. So much so that I think you should really watch all of Season 55, with their big feelings curriculum, because I sense you have a very big feeling inside of you.
