This is not exactly propaganda in the typical sense, but it clearly is the case that people successfully edit Wikipedia to further objectives. As an example, the Wikipedia page for Meta-analysis (which isn't even that obscure of a topic) currently contains content that seems to plausibly be trying to promote Suhail Doi's methods, and it seems that it has been like this for a number of years. It cites 5 papers from him, more than anyone else, of which the largest has 297 citations. It has a subsection devoted to his method of meta-analysis, despite it being a rather obscure and rarely used method. There have been additional subsections added over time, which also focus on somewhat obscure areas, but frankly these additions are sketchy in similar ways.

In general, it is not uncommon to come across slantedness issues. Is it completely 100% clear that Doi has come on and maliciously added his papers? Not quite, but good propaganda wouldn't be either, and would actually be far less suspicious-looking.

A lot of embedding models are built on top of T5's encoder, this offers a new option

The modularity of the enc-dec approach is useful - you can insert additional models in between (e.g. A diffusion model), you can use different encoders for different modalities, etc

That tweet had it backwards, more tokens in tokenizer means that the 16k token context window typically allows for even longer passages than if LLaMA were 16k

phi-1 is a code-specific base model, with further finetuning on top of that. This is a general language base model, not really comparable.

RWKV also uses some sort of L2-esque regularization, which was supposedly an idea taken from PaLM (although I can't find a source on this point, other than some message in the RWKV discord)

Training as GPT vs RNN will give you numerically identical results with RWKV, it's just two ways of computing the same thing. It's trained in GPT-mode because it's cheaper to train that way -- you can parallelize over the sequence length. In practice it isn't going to be any different than training with back-propagation through time for the same sequence length.
