It’s fine but given the relatively small price difference between that and whey, I’d go with whey every time as it’s a more complete protein source.

that said, I’ve been advising to avoid matrix for the last 10 years.

Soy in small amounts is fine.you just don't want to replace your regular protein sources with it as its an inferior protein source compared to whey,eggs,meat etc.as @faipdeooiad  and @OptimumPTave pointed out.

The main issue with soy protein is in the manufacturing process.one of the cheaper manufacturing processes uses a solvent called hexane which isn't the best option.by consuming soy in large amounts you also consume the associated phyates, trypsin inhibitors and phytoestrogens the are contained in a lot of all in one protein powder and protein bars.

Manufacturers use soy as its a cheaper protein source,which obviously increases their profit margins.soy can also help to extend the shelf life of protein bars,also.
