The underlying principals of SOA haven't been dismissed.

However, there have been some rather bad implementations of SOA that have been passed off as 'how to do SOA'. When enough people started using, for example, web-services without thinking about how to handle something as common as a network partition, those people became disenchanted with the terms SOA and micro-services.

SOA became synonymous with web services, same with micro services. The service bus or message queue is still missing in most places.
