Yes, they're owned by Alibaba. I happen to know some SCMP employees which gives me confidence that they're still editorially independent. They of course have a pretty pro-status-quo stance, and I don't recommend on relying on them entirely as your only source of information, but I don't believe China has any editorial influence.
(Also important to note Alibaba isn't necessarily in the CCP's best graces lately.)

> On 30 August, the Polish Navy sent its destroyer flotilla to Britain, executing the Peking Plan. On the same day, Marshal of Poland Edward Rydz-Śmigły announced the mobilization of Polish troops. However, he was pressured into revoking the order by the French, who apparently still hoped for a diplomatic settlement, failing to realize that the Germans were fully mobilized and concentrated at the Polish border.
