True in essence, but OSS is not necessarily synonymous with privacy, security or reliability, this only depends on the developer and the intentions of this and maintenance. There is nothing more dangerous than an unattended OSS, precisely because the code is public and not everyone who reads it has good intentions. On the other hand, not all proprietary software is automatically garbage, abusive or spyware, if we exclude those from the BigBrother companies. In each software or service, regardless of whether it is OpenSource or not, it is always important to read the TOS and PP, if people did, they would often be surprised and not always pleasant. FOSS is always preferable, but do not cling to the fact that it is the universal panacea, it is not, it's the common sense.
