Clownski_: […] When you give us consent for direct marketing communications, we will use the services of our Trusted Partners to allow for direct, online communications through third-party services […]
lupineshadow: If the email address is truly hashed and anonymised and no other coincidental linked data is sent to google/facebook at the same time (such as user agent, screen resolution) which can absolutely be used to fingerprint users when you have the reach and resources as google/facebook - then it's ok. Not user-friendly but not abusive.
I wouldn't count on that "hashed" or "anonymity". Especially if one have the same Email Address for GOG and Google:
About the customer matching process How it works
You create a customer data file based on information shared by your customers.
To keep your data secure, you can hash your customer data yourself using the SHA256 algorithm, or Google Ads will hash the data for you using the same SHA256 algorithm, which is the industry standard for one-way hashing
Google even have this hashed value of the Google user's email address recorded. They did said so:
Email address and phone matching
Google keeps track of the email addresses and phone numbers for Google accounts and the corresponding hashed strings for those email addresses or phone numbers.
After you've uploaded your customer list of email addresses and/or phone numbers, Google Ads will compare each hashed string on your customer list with the hashed string for email address or phone number of Google accounts. If there's a match, Google adds the corresponding Google account to your Customer Match segments (Customer list).
And sure enough, they have their guarantees:
• Limited data use. We won’t use your data files for any purpose other than to create your Customer Match audiences and ensure compliance with our policies. We won’t use your data files to build or enhance profiles of your customers.
• Limited data access. We won’t share your data files with other Google teams other than to create your Customer Match audiences and ensure compliance with our policies. We use employee access controls to protect your data files from unauthorized access.
• Limited data sharing. We won’t share your data files with any third party, including other advertisers. Google may share this data to meet any applicable law, regulation, legal process or enforceable governmental request.
• Limited data retention. We won’t retain your data files for any longer than necessary to create your Customer Match audiences and ensure compliance with our policies. Once those processes are complete, we'll promptly delete the data files you uploaded via the Google Ads interface or the API.
…followed by:
[…] As with other Google advertising products, we may use information derived from impressions or clicks on Customer Match ads to improve Google Ads and other Google products and services.
Note: About the '
Limited data retention.', the data files they mention that they would delete will be the user's Email Address to be handed by GOG in this case, not the 'Customer Match data' that will be created by the whole process.
There's also one for Facebook, but I couldn't be bothered skimming.

lupineshadow: 2: if you trust google. Most of us do not trust google but they are your trusted partners...so GOG by association can't be trusted.
"Trusted Partners" in this context is more of an "assurance" to the users in their wording.
Not that they trust them or anything. (nor it was reassuring)
