Neither are projects at the Eclipse Foundation, and neither are part of m2e proper.
Fred Bricon worked on m2e-wtp in his free time and now works on it for JBoss. Webby is a project that Sonatype developed internally to make Maven-based webapp development easier for us. Then we open sourced it. Webby is for simple webapps, m2e-wtp covers the full JEE usecases. The codebase for Webby is much smaller but is limited in its scope, it was fun and we just hacked it together making small modifications to Cargo (which we contributed back). m2e-wtp is professionally supported by the JBoss folks through the JBoss tools.
