In terms of what content you can see, the difference between Lemmy and PieFed is effectively the same as the difference between two Lemmy instances. As long as the instances federate with one another, it does not matter which platform you use. You can definitely interact with PieFed from Lemmy just fine. In fact, you are doing so right now! My account is on a PieFed Instance.
This meme is more making a joke about how relatively young PieFed is. Years back, a post to any community on the fediverse that got 20 upvotes was huge. But today, a post with 20 votes is basically nothing (depending in the size of the community). By the time PieFed came about, the fediverse was populated enough that a post with only 20 votes was nothing like a post with 20 votes in the olden days of Lemmy.
