Bad news in general if you want to use WordPress for government work, or just want to provide accessible services:
Studio24 cited accessibility as the deciding factor. Automattic has already signaled accessibility is not a priority for it or its investment in Gutenberg. The community had to crowd-fund an audit, all while Gutenberg was pushed to final public release with dozens of known accessibility issues. The entire time, all the accessibility work was done by volunteers, not supported by Automattic’s $3 billion bulk in any meaningful way.
