Good question and I would like to share more background with you all :)
The open source API Gateway project, APISIX, was open sourced and donated to Apache Software Foundation by API7.ai[1] in 2019, many people asked why not use Kong, AWS or other products? The main reason was Kong relies on PostgreSQL and AWS Gateway is vendor locked, now Kong has supported the DB less deployment mode, Apache APISIX also supports this way, this mode is easy to maintain with GitOps.
